우러 겨례는 항시 공산군의 침략적인 야욕을 북으로부터 이중적 위협, 즉, 직접침략과 간접침략의 본질을 인식함으로써 이를 근본적으로 대처하고 분체할 수 있는 노력을 범 국민적으로 경주해야할 것이며 국토 방위의 임무에는 너, 나가 따로이 있는 것이 아님을 깨달아야 하겠다. 전략론의 저자인 B.H 리틀 하아트는 “평화를 원하거든 전쟁을 이해하라, 아는 것이 준비하는 것이다.” 라고 하였다. 이것은 진정한 평화, 즉, 전쟁을 싫어하자면 국방을 튼튼히 하고 외세의 침략을 초기에 분체할 수 있는 힘을 길러서 자주국방을 튼튼히 해야 한다는 것이다.

三角測量의 誤差調整方法에 관한 硏究

林采文,洪益相 대구대학교 기초과학연구소 1993 基礎科學硏究 Vol.10 No.-

Triangulation is a mode of survey performed to decide with precision through triangulation the position of triangulation station, a basic point, which constitutes the frame in traugsing, topographic survey, cadastral survey and others. For each triangulation station in triangulation, the survey of all angles should satisfy the three conditions. No matter how prudently observed, there will always be errors and the three conditions are not fulfilled, so all the observed angles should be adjusted to satisfy the above conditions, In this study, adjustment, adjustment value and precision are attemped for review by means of approximate method and angle equation of horizontal in triangulation of central triangular net which will decide one point from already known triangulation station.

회전축계의 진동제어용 ER 유체 댐퍼의 설계 및 반능동 비례제어

This paper is concerned with the design and application of an Electro-Rheological(ER) fluid damper to suppress vibration of rotor systems. The example system at hand is flexible with a slender shaft and a thin disk, being su pported by two ball bearings. In addition, to investigate the system performances also in the high speed range, the driving torque is made to transmit through a speed increasing gear train. Along with the experiments, to predict and compare the ER damper effect, the rotor system is simulated as to its free and forced vibration characteristics. Such simulations are done by means of a finite element analysis code, which includes the mathematical model of the designed ER damper.

This paper explores the research under way in developing an automatic measuring of a navigation by Global Positioning System(GPS) technique with equipped NavTrac model(manufactured by Trimble Ltd.). An experimental cruising assess the accuracy of the GPS for the dimentional navigation. The GPS position was analyzed in terms of the plane coordinates(X,Y), which are gained the transformation of WGS-80 to Tokyo coordinate. From results of the test cruising, differenes between actual and cruised are did not exceed±25m. This error bound assumed to be an heuristic discriminative region at 1/25,000 base map. The use of this GPS positioning technique would be well suited for a variety of application where cost effectiveness becomes an importance factor.

The purpose of this study is to estimate a suitable traveling speed model based on using the traffic data collected by test-vehicle traveling method and the data on road geometric and operating characteristics. The conclusions of this study are as follows. In travel speed model(Q-V), regression model (V=9.635+0.0169L - 0.00045Q - 2.1926N, R²=0.76) the important independent variables are speed is closely related with distance, traffic volume and the number of traffic lane, form the result of speed-flow regression analysis, link travel speeds are influenced by link distance, traffic volume, and the number of lanes. As expectedly by the most significant factor influencing link travel speeds. The changing of traveling speed according to section distance is appeared large. According to the result of analysis of travel speed and traffic density model(Q-K), as according the that density increases the travel speed is decreases, on the other hand travel speed increases, the density decreases. The speed equation (u=68.72e^(-k/22.6)) is derived by form the Q-K relationships founded form the study, traffic volume increases as traffic speed increase up to the critical traffic density. If traffic volume decreases when traffic density is abduce the critical traffic density. Using Q-V equation estimated by regression analysis and Q-K equation estimated by density, Traffic value test was accomplished by computer program(TRANPLAN). There were difference between too test, however, the deviation was small. On case of using program, the application extent we considered, is between 25Km/h - 60Km/h. Traffic volumes obtained from TRANPLAN are governably 10% larger than traffic volume estimated form Q-K model. However the difference of the critical traffic density bow Q-K model and TRANPLAN, are relatively small. It is desirable to reduce traffic volume by 0.7∼9% over all, speed range when TRAPLAN is applied in Q-K relationship.

동시성을 보장하는 고성능 B+-트리 재구성 알고리즘

임성채 同德女子大學校 情報科學硏究所 2005 정보과학연구 Vol.9 No.-

데이터베이스 시스템의 성능향상을 위해 높은 동시성을 보장하는 B-트리 색인 구조에 대한 연구가 있어왔다. 제안된 트리 재구성 기법은 언제나 B+-트리의 일관성을 유지하기 때문에 범위 검색자를 포함한 모든 검색 프로세스들은 잠금을 전혀 사용하지 않고도 키 검색을 할 수 있다. 논문에선 단말노드에 만들어진 링크 연결을 올바로 유지하기 위해 범위 표시자라는 필드가 쓰이며, 이 필드들을 통해 효과적인 트리 재구성과 범위검색이 가능하다. 제안된 B+-트리는 아직 완료되지 않은 프로세스에 의해 갱신된 노드에 대해서는 다른 프로세스가 갱신동작을 하지 못하게 함으로써, 레코드 단위의 redo/undo기법을 기반으로 하는 B+-트리 복구기능을 지원한다. As the B-tree index could be a performance bottleneck in database systems, concurrent B-tree algorithms have been intensively studied to improve concurrency of B-tree accesses in the literature. In this paper we propose a new concurrent B+-tree algorithm providing high concurrency and an efficient tree restructuring method. Because the proposed method of tree restructuring always preserves a semantic consistency of the B+-tree, a key searcher need not require any lock for a range search as well as a single-key search. To maintain correctly the link fields constructed at the leaf level, we make each leaf node contain two key-range indicators, and develop a tree restructuring method using these key-range indicators. In addition, since we prevent update processes from accessing nodes updated by others that do not commit, recovery capability is easily established using the record- oriented redo/undo.

Five elements motion and six kinds of natural factors influence not only human disease but also difference of medicine effect. Because the climate of summer is very hot, that is easy to increase the properties of hot medicines, a doctor must be careful to use it in summer. Also the climate of winter is very cold, that is easy to increase the properties of cold medicines, a doctor must be careful to use it in winter. But in the certain conditions to use diaphoretics or purgatives, in spite of that regulation a doctor can use them.

This study was aimed to establish the system of centers and to offer the viewpoint to studies and policies of urban spatial structure while analyzing their characteristics in Busan. The results of this study were summarized as followed : According to the result about the establishment of the system of centers, 2 Centers, 4 Sub-Centers and 5 low-lanking centers were identified. This is a little different with 2 Centers, 6 Sub-Centers, 2 District-Centers written in 「Busan Master Plan toward 2011's」. In other words, the system of centers in Busan was represented more subdivided and abundant than that of 「Busan Master Plan toward 2011's」 and these centers had both polycentric and multi-nuclei characteristics. With premise that the urban structure is being changed on the basis of the change of a period, society and an economy in the future to establish effective system of centers, it is advisable that the establishment of the system of centers is to readjust by stage in the process of planning.
